Look at the reflection in the diner's window at the beginning of the trailer.
Over on the right side of the window... does that look like the reflection of something resembling the Zodiac Key to anyone else?

....eye patch, really? Tony Stark built a robot suit in a fuckin' cave using a pair of plyers and a rocket!!!!!!!!! Surely now he's back in his high tech fuckpad/palace he can make Fury a bionicy eye thingy, Fury should tell stark he's got naked pictures of Black Widow...oh, wait.....WE ALL HAVE MUVAFUKKA!!!!!!!!!!!!!!!!!

but we have to leave something for the sequels don't we? ;p
I'm guessing we'll see bits and pieces of Tony building Vision throughout Avengers if not in a sequel.
Personally I'm more excited for an Avengers 3 if they're able to assemble the entire team.. Ant/Giant-Man, Vision, T'Challa, and Wasp included.

That trailer is at best cliched and standard. Even Scarlet is doing the cliched boring crouched down on one knee pose! The lighting and cinematography seems flat. So what is the big deal..? I need it explained!

no not really. In fact if other movies are any kind of example of this kind of thing, putting in too many characters doesn't really work. Apart from The Magnificent Seven!
Too little screen time for any given character for you to give any shit about and therefore what you end up with is a Michael Bay mess!
Also it doesn't answer my other question of all the cliched shots in that trailer!

I love Marvel, grew up on these comics, but there's something not right. In my heart I feel like there's something cheap and generic about this movie. Don't get me wrong, I'll be first in line, but I don't feel any epicness to the trailer. It looks cheap like the two FF movies. I blame marvel studios, they're trying to make these movies as big as possible for as cheap as possible and to me it shows. Warner bros is doing batman on a grand scale, Disney should do the same with the avengers, there's no bigger marvel franchise!

I don't really think this movie will be better than Iron Man 1 or Captain America, but I'm still excited about having all these characters together in one movie. As a lifelong Marvel fan that's where I'm coming from. I do hope that this baby is 2 1/2 hours so they have enough time for the origin story and to give all the characters enough time to shine. Plus the Spider-man movie looks like it will be shit, so I'm pinning all my hopes for this year on the Avengers!

I think you got the jist of what I meant and still decided to be a dick to score points. I was hardly going to list every single film but was merely pointing out something.
This film still looks like shit though!

Not a lot of info, but there you go. I was feeling bad for Clark Gregg halfway through reading that, but it looks like people finally realized he was there.
